With the WSS/SharePoint April 2009 Cumulative Update, a new parameter was introduced for the “stsadm –o deletesite” and “stsadm –o mergecontentdbs” commands. I noticed it while reviewing some recently published/update TechNet articles and tweeted about it here, here, here and here. Because of that I wanted to summarize the content in one post, point out some other things I found while researching and point you to where you can get more detail. On The Sean Blog, Sean covers all the commands added in the April update.
